The Galaxy S21 Ultra is Samsung's 2021 flagship phone, with a 6.8-inch 1440p AMOLED screen that runs at 120Hz, a 5,000 mAh battery and a quad rear camera built around a 108MP main sensor and two telephoto lenses with 3x and 10x optical zoom. It was the first Galaxy S phone to support the S Pen, sold separately, and it still holds up on screen, zoom and build against newer rivals. Reviewers praised the display and camera flexibility but flagged the size, the weight and the Exynos version's heat and battery drain in some markets. It suits people who want a big, capable Android phone with strong zoom and a stylus option, and who accept a heavier device with only 128GB of storage here.
